Abstract
The aim of the study was to assess the macrostructure and the microstructure of the bladder and urethral mucosa in dogs with lower urinary tract disease as well as to evaluate the usefulness of the WHO/ISUP grading of invasive and non-invasive tumours of the bladder and urethral mucosa. The study was carried out on 37 dogs of different breeds and of both sexes, from 9 months to 15 years old. An urethrocystoscopy and a histopathological evaluation of mucosal biopsies were carried out in all the studied dogs. Cystitis was the most common disease noted during urethrocystoscopy. Chronic active inflammation of the bladder was the most common inflammatory lesion diagnosed in the histopathological examination, while the transitional cell carcinoma was the most common tumour of the bladder. Urethrocystoscopy proved to be a very useful tool in the assessment of macroscopic lesions in the bladder and urethral mucosa in dogs. We also evaluated the type and extent of microscopic inflammatory lesions in the bladder and urethral mucosa using the modified Sydney scale. The WHO/ISUP scale is very helpful in the histopathological classification of canine invasive and non-invasive proliferative lesions in the bladder and urethra.

Abstract
Dynamic contrast enhanced (DCE)-magnetic resonance imaging (MRI) consists of acquisition of native baseline images, followed by a series of acquisitions performed during and after administration of a contrast medium. DCE-MRI, in conjunction with hepatobiliary-specific contrast media, such as gadoxetic acid (GD-EOB-DTPA), allows for precise characterisation of the enhancement pattern of the hepatic parenchyma following administration of the contrast agent. The aim of the study was to assess the pattern of temporal resolution contrast enhancement of the hepatic parenchyma following administration of GD-EOB-DTPA and to determine the optimal time window for post-contrast assessment of the liver. The study was carried out on eight healthy beagle dogs. MRI was performed using a 1.5T scanner. The imaging protocol included T1 weighted (T1-W) gradient echo (GRE), T2 weighted (T2-W) turbo spin echo (TSE) and dynamic T1-W GRE sequences. The dynamic T1-W sequence was performed using single 10mm thick slices. Regions of interest (ROIs) were chosen and the signal intensity curves were calculated for quantitative image analysis. The mean time to peak for all dogs was 26min. The plateau phase lasted on average 21min. A gradual decrease in the signal intensity of the hepatic parenchyma was observed in all dogs. A DCE-MRI enhancement pattern of the hepatic parenchyma was evident in dogs following the administration of a GD-EOB-DTPA, establishing baseline data for an optimal time window between 26 and 41min after administration of the contrast agent.

Abstract
Haematopoiesis is one of the most well understood stem-cell associated processes. It is a process in which pluripotent hematopoietic stem cells (HSCs) self-proliferate and differentiate into all types of blood cells. The process takes place in marrow of the flat bones in adults, however its location changes several times through embryonic and foetal development. Given the broad range of blood cells and the major differences in their build and function, together with the fact that their numbers need to be maintained within relatively narrow margins in order to maintain homeostasis despite changing environmental conditions, makes the whole process of haematopoiesis highly regulated and depending on a variety of growth factors. When influenced by those, HSCs undergo several irreversible steps, with every next one committing them to an even more specialised fate, ending with all the specific types of mostly short-lived blood cells, that are unable to proliferate on their own and need constant replenishment from the HSC pool. Because the process of haematopoiesis is the only source of all the members of the group of cells performing a range of highly important roles in functioning of the organism, significant damage to the underlying stem cells can cause a range of severe diseases. Many treatments are suggested for managing their symptoms or slowing progress, with bone marrow transplant being one of the only ones that offer possible permanent solution and, despite being a relatively risky procedure, is being widely performed, with the methods constantly improving in order to achieve progressively better results in both treatability and survivability of the patients.

Abstract
Summary
N-homocysteinylated (Nε-Hcy) proteins and corresponding antibodies have recently been discovered in humans and animals. Increased autoimmune response to Nε -Hcy-proteins has been reported in stroke patients. The aim of the present study was to investigate whether antibodies against N-homocysteinylated albumin are associated with coronary artery disease (CAD).We studied 88 male patients aged 50 years or under with angiographically documented CAD and 100 age-matched apparently healthy men as controls. Serum levels of IgG antibodies against Nε-Hcy-albumin were determined using an enzymelinked immunosorbent assay. Seropositivity to anti-Nε -Hcy-albumin antibodies was 5-fold more frequent in CAD patients than in controls (52.3 % vs 10.0 %; p<0.0001). Plasma Hcy levels in CAD patients were also significantly higher in the former than in the latter group (medians, 13.0 μ M vs 12.1 μ M; p=0.026). Importantly, 41.2% of subjects with plasma total Hcy >14.5 mM were seropositive compared with 25.5 % of normohomocysteinemic individuals (p=0.048).There was a weak correlation between anti-Nε-Hcy-albumin antibodies and Hcy levels (r=0.16; p=0.03). By multivariate logistic regression analysis, seropositivity to anti-Nε-Hcy-albumin antibodies was an independent predictor of early CAD (OR, 14.82; 95% CI, 4.47 to 49.19; p=0.00002). Interestingly, anti-Nε-Hcy-albumin antibodies were associated with C-reactive protein levels (r=0.24; p=0.002). Seropositivity to anti-Nε-Hcy-albumin antibodies showed no association with the MTHFR C677T polymorphism. Our results suggest that seropositivity to antibodies against Nε-homocysteinylated albumin is associated with early-onset CAD. An autoimmune response to Nε-Hcy-albumin may represent a novel mechanism involved in the early development of CAD.

Abstract
AbstractThe aim of this study was to assess the suitability of invasive and non-invasive methods used to diagnose Helicobacter spp. in the stomachs of dogs. The study was carried out on 30 dogs of both sexes and different breeds, between one and 15 years old. A histopathologic examination, a microbiological culture, a rapid urease test, a direct bacteriological preparation and a nested PCR assay were carried out. Gastric Helicobacter spp. was identified in gastric biopsy specimens from 16 (53.3%) dogs using direct bacteriological preparation, in four (13.3%) dogs based on a culture, in 23 (76.6%) dogs using the rapid urease test and in 21 (70,0%) dogs based on a histopathological assessment of the biopsy specimens. The nested PCR of the gastric biopsy specimens revealed gastric Helicobacter spp. in all the dogs (100%). A saliva PCR assay revealed gastric Helicobacter spp. in 23 (76.6%) dogs, while stool PCR revealed the bacterium in seven (23.3%) dogs. We found that invasive methods were more accurate than non-invasive methods in detecting a Helicobacter spp. infection in dogs. In addition, the nested PCR method used to evaluate the gastric mucosal biopsy specimens was the most accurate test for detecting Helicobacter spp. It was further found that the PCR-based saliva assay was the best non-invasive method for detecting Helicobacter spp. However, taking into consideration that most of the diagnostic methods used to detect this bacterium have drawbacks, at least two diagnostic methods should be used to detect Helicobacter spp. as is done in human medicine.

Abstract
Of all the tumours in dogs, three percent are located in the intestines, and 36-60% of those tumours affect the large intestine. Adenocarcinomas of the intestines account for 20-35% of the gastrointestinal tumours and for almost 60% of the large intestine tumours. The aim of the study was to analyze clinical disorders and endoscopic, histopathological and immunohistochemical changes in colorectal adenocarcinomas in dogs with the use of the E-cadherin, β-catenin, cytokeratin 20 (CK20), Ki-67 and minichromosome maintenance 3 (MCM-3). The study comprised 11 dogs of both genders and of different breeds diagnosed with adenocarcinoma of the large intestine. They were from 4 to 11 years old. The large intestine adenocarcinoma was diagnosed in all the patients. 72.7% cases were diagnosed with a rectal adenocarcinoma, and 27.3% were found to have a colonic adenocarcinoma. All the studied proteins were expressed at different levels and, together with the histological findings, indicated different levels of malignancy (G). The statistical analysis revealed no statistically significant differences between the expression of E-cadherin and β-catenin in the studied tissues (p=0.79) and between the expression of Ki-67 andMCM-3 (p=0.39). A strong positive correlation was found between the expression of E-cadherin and β-catenin (r=0.86; p<0.05). The diagnosis of adenocarcinomas of the large intestine may be facilitated by the introduction of immunohistochemical studies using appropriate cell markers. They may also aid in the accurate evaluation of the biological character of the tumours, their origin, the connections between tumour cells and the mitotic index. That, in turn, may help determine the malignancy and the choice of treatment.

Abstract
BACKGROUND Allergic reaction to seminal plasma was described decades ago. In USA, only tens of thousands women are estimated to be affected. Not only seminal plasma but also cervicovaginal fluid contains sex-restricted antigens, yet allergy to cervicovaginal fluid has never been reported in medical literature. We came to a suspicion that because immunologic tests required to prove such a diagnosis, allergy to cervicovaginal fluid has never been reported yet it is not uncommon. OBJECTIVE The objective of this study was to use an Internet-based questionnaire to characterize the population of men with suspected hypersensitivity to cervicovaginal fluid. METHODS A questionnaire designed to cover localized and systemic symptoms of hypersensitivity reaction was made available via the Internet. Respondents with postcoital adverse reactions were invited to participate. Only respondents who presented with at least two symptoms suggestive to hypersensitivity to seminal plasma or cervicovaginal fluid and were negative for STI, and known hypersensitivity reactions such as latex allergy were a subject for further analysis. Board-certified dermatologists were surveyed for seeing bona fide cases of cervicovaginal fluid hypersensitivity. RESULTS We have identified 52 cases of suspected hypersensitivity to cervicovaginal fluid (CVF). Both localized and systemic types of hypersensitivity were identified. A substantial number of dermatologists admitted to witnessing cases of hypersensitivity to CVF. CONCLUSION Based on data from affected individuals as well as the opinions of dermatologists worldwide, we believe that allergic reaction to cervicovaginal fluid is at least as common as seminal plasma allergy. However, remains unreported due to technical difficulties in diagnosis and dermatologists' disbelief in its actual existence.

Abstract
BACKGROUND The coeliac trunk (CT) is major visceral branch of the abdominal aorta. Familiarity with anatomic variations of the CT is relevant for planning radiological and surgical procedures. The aim of our research was determining variations of the CT, including the occurrence of accessory hepatic arteries (AHA). MATERIALS AND METHODS Forty cadavers were studied. Six patterns of CT branching were observed in this study. AHA were observed in 7 (17.5%) specimens. The most prevalent variation was normal trifurcation, accounting for 62.5% of cases. The rarest variation was absence of the CT, with an incidence of 2.5%. In this variant the left gastric artery, the common hepatic artery, and the splenic artery branched directly off the abdominal aorta. RESULTS The study material allowed to distinguish two CT branching patterns which, to the best of our knowledge, have not been reported before. It was a type with four branches originating from the CT: the left gastric artery, the common hepatic artery, the splenic artery, and right AHA. The other previously unreported pattern variant was the CT which gave off three branches: the common hepatic artery, the splenic artery and right AHA. CONCLUSIONS The average distance between the aortic hiatus and the coeliac trunk calculated for all the cadavers amounted to 54 ± 11.85 mm. The average distance between the CT and the superior mesenteric artery was 11.1 ± 7.7 mm.

Abstract
Shear wave elastography is a novel technique enabling real-time measurement of the elasticity of liver tissue. The color map is superimposed on the classic ultrasound image of the assessed tissue, which enables a precise evaluation of the stiffness of the liver tissue. The aim of the study was to assess the stiffness of normal liver tissue in the guinea pig using shear wave elastography. The study was carried out on 36 guinea pigs using the SuperSonic Imagine Aixplorer scanner, and a 1 to 6 MH convex SC6-1 transducer. An ultrasound guided Try-Cut liver core needle biopsy was carried out in all the studied animals and the collected samples were examined to exclude pathological lesions. The mean liver tissue stiffness ranged from 0.89 to 5.40 kPa. We found that shear wave elastography is an easy, non-invasive technique that can be used to assess the stiffness of liver tissue. The obtained results can be used in future studies to assess the types and changes of liver tissue in the course of various types of liver disease.

Abstract
The aim of this study was to assess whether the serum levels of the 7S fragment of type IV collagen may aid in diagnosing liver fibrosis in dogs. The study was carried out on 20 dogs with liver disease. Serum levels of the 7S fragment of type IV collagen were measured in all dogs. The analysis showed that healthy dogs and dogs with type 1, 2 and 3 liver fibrosis had low serum concentrations of the 7S fragment of type IV collagen compared to dogs with type 4 liver fibrosis. The study revealed that the assessment of serum levels of the 7S fragment of type IV collagen is useful in the diagnosis of advanced liver fibrosis and cirrhosis.

Abstract
The aim of the study was to evaluate the serum concentration of the type III procollagen aminopeptide in dogs, and to assess its utility in the diagnosis of liver fibrosis. The study was carried out on 20 dogs of different breeds and of both genders, between 7 and 15 years old. Based on the results of the histopathological examination and the evaluation of the degree of liver fibrosis, the dogs were divided into five groups. The mean serum PIIINP concentration in the group of dogs with stage 1 and 2 liver fibrosis (groups 2 and 3) was five-fold higher than in healthy dogs (group 1). In turn, the mean PIIINP concentration in the group of dogs with stage 3 (group 4) and stage 4 (group 5) fibrosis was 10-fold higher than that of the control group (group 1). Based on the results, we found that the serum PIIINP concentration correlated with the degree of liver fibrosis, assessed based on a histopathological examination. Therefore, PIIINP serum concentration tests may be a promising non-invasive diagnostic technique that could be used in veterinary hepatology to assess the degree of liver fibrosis.

Abstract
INTRODUCTION Rectal cancer is the most common malignant neoplasm of the gastrointestinal tract. The aim of the study was to assess the quality of life in patients undergoing surgical treatment for the rectal cancer, either lower anterior or abdominoperineal resection. MATERIALS AND METHODS 100 patients suffering from rectal cancer were selected for a prospective study (50-APR, 50-LAR). The quality of life was assessed two times: at the admission to the Department and 6 months following surgery. For assessment of the quality of life, two standard questionnaires were used, EORT QLQ-C30 and EORTC QLQ-C29. RESULTS The studied groups were not different with respect to demographic factors. The patients who underwent LAR spent less time in hospital (p = 0.00001). The patients undergoing APR scored less with respect to physical ability (p = 0.0434), cognitive (p = 0.0363) and emotional state (p = 0.0463) and on symptom scale (nausea and vomiting - p: 0.0199, diarrhea - p: 0.0000, constipation (p = 0.0018)); however, the patients who were treated with LAR scored less on pain scale (p = 0.0189). The QLQ-C29 questionnaire revealed impaired functioning of patients 6 months following APR in terms of life chances (p = 0.0000) and problems with body weight (p = 0.0212). In both groups, the quality of life improved 6 months after surgery. CONCLUSIONS LAR is a chance for better quality of life for many patients. Six months after surgery, the quality of life of patients improves regardless of the operating method (APR, LAR).

Abstract
BACKGROUND Improvements in local control are required when using preoperative chemoradiation for cT4 or advanced cT3 rectal cancer. There is therefore a need to explore more effective schedules. PATIENTS AND METHODS Patients with fixed cT3 or cT4 cancer were randomized either to 5 × 5 Gy and three cycles of FOLFOX4 (group A) or to 50.4 Gy in 28 fractions combined with two 5-day cycles of bolus 5-Fu 325 mg/m(2)/day and leucovorin 20 mg/m(2)/day during the first and fifth week of irradiation along with five infusions of oxaliplatin 50 mg/m(2) once weekly (group B). The protocol was amended in 2012 to allow oxaliplatin to be then foregone in both groups. RESULTS Of 541 entered patients, 515 were eligible for analysis; 261 in group A and 254 in group B. Preoperative treatment acute toxicity was lower in group A than group B, P = 0.006; any toxicity being, respectively, 75% versus 83%, grade III-IV 23% versus 21% and toxic deaths 1% versus 3%. R0 resection rates (primary end point) and pathological complete response rates in groups A and B were, respectively, 77% versus 71%, P = 0.07, and 16% versus 12%, P = 0.17. The median follow-up was 35 months. At 3 years, the rates of overall survival and disease-free survival in groups A and B were, respectively, 73% versus 65%, P = 0.046, and 53% versus 52%, P = 0.85, together with the cumulative incidence of local failure and distant metastases being, respectively, 22% versus 21%, P = 0.82, and 30% versus 27%, P = 0.26. Postoperative and late complications rates in group A and group B were, respectively, 29% versus 25%, P = 0.18, and 20% versus 22%, P = 0.54. CONCLUSIONS No differences were observed in local efficacy between 5 × 5 Gy with consolidation chemotherapy and long-course chemoradiation. Nevertheless, an improved overall survival and lower acute toxicity favours the 5 × 5 Gy schedule with consolidation chemotherapy. CLINICAL TRIAL NUMBER The trial is registered as ClinicalTrials.gov number NCT00833131.

Abstract
The aim of the study was to assess pH, pO2 and pCO2 in peritoneal fluid. The study was conducted on a group of 22 dogs with symptoms of ascites. Group 1 consisted of 4 dogs with adenocarcinoma, group 2--of 6 dogs with glomerulonephritis, group 3 of 8 dogs with hepatic cirrhosis and group 4 of 4 dogs with bacterial peritonitis. An abdominal cavity puncture was performed in all dogs and the fluid was drawn into a heparinized syringe in order to assess pH, pO2 and pCO2 . The analysis of pH in the peritoneal fluid revealed statistically significant differences between group 4 and groups 1 (p=0.01), 2 (p=0.01), and 3 (p=0.01). The lowest pH value compared to the other studied groups was recorded in group 4. In group 4, the pO2 was the lowest compared to the other groups (group 1 p=0.01, group 2 p=0.01, group 3 p=0.01). The value of pCO2 was the highest in group 4 compared to groups 1, 2, and 3. The study found statistically significant differences in pH, pCO2 and pCO2 between group 4 (the group of dogs with bacterial peritonitis) and the other groups of dogs. This was probably linked to the pathogenesis of peritonitis. As a result of an inflammatory reaction within the peritoneal cavity, there is an increase in fibrin accumulations leading to a decreased oxygen supply causing the oxidative glucose metabolism to change into a non-oxidative glucose metabolism. This, in turn, causes a decrease in pH, acidosis, and a low oxidoreduction potential. It also impairs phagocytosis and activates proteolytic enzymes which create ideal conditions for the growth of anaerobic bacteria. The obtained results indicate that the pH, pO2 and pCO2 may be used to differentiate bacterial peritonitis from ascites of other etiologies.

Abstract
Plasma filtration through glomerular filtration barrier (GFB) is a key process to maintain fluid and electrolyte homeostasis. GFB consisting of endothelial cells, podocytes and basement membrane restricts passage of albumin but is permeable for smaller plasma molecules. Various biological agents, such as extracellular nucleotides influence activity of cells, which in turn affects permeability of GFB. Nucleotides are released from cells outside and within the glomeruli that activate the purinoceptors - P2Rs classified into ATP-gated non-selective ion channels, P2X receptors (P2XRs), and G-protein-coupled metabotropic P2Y receptors (P2YRs). P2Rs are expressed on cellular components of GFB. P2Rs activation triggers intracellular calcium concentration and calcium-dependent metabolism with subsequent affect on glomerular permeability to albumin. Purinergic-dependent glomerular cell activation also affects the biophysical properties of acelluar glomerular basement membrane (GMB). Finally, P2Rs stimulation may lead to increased proteins excretion in urine. The involvement of P2Rs in increased GFB permeability to albumin may be expected under pathophysiological conditions characterized by increased albumin excretion in urine.

Abstract
There are multiple dynamic changes associated with the metabolism of the extracellular matrix (ECM) which occur in the course of liver fibrosis. Therefore, the evaluation of parameters reflecting the deposition of ECM, the activity of myofibroblasts and the synthesis and degradation of collagen may aid in the diagnosis of liver fibrosis. Hyaluronic acid is considered to be a marker of ECM deposition. It is a glycosaminoglycan synthesized by hepatic stellate cells and degraded by hepatic sinusoidal endothelial cells. The aim of this study was to evaluate the concentration of hyaluronic acid in dogs with different degrees of liver fibrosis. The study was carried out on 29 dogs with liver disease. A core needle biopsy of the liver was performed in order to assess the degree of hepatic inflammation. Then, hyaluronic acid serum concentrations were measured. The dogs were divided into five groups based on the histopathological examination and the evaluation of the degree of hepatic fibrosis. The study showed that serum hyaluronic acid concentrations were low in patients with first stage liver fibrosis and in controls, while they were twice as high as control values in the group of dogs with second stage liver fibrosis. These concentrations were three-fold greater than control values in patients with third stage liver fibrosis, and seven-fold greater in patients with liver cirrhosis. Based on the results, it was concluded that serum hyaluronic acid is a useful marker of liver fibrosis and may aid in determining the degree of its advancement.
